Abstract

The invention relates to a micro-open-type safety valve displacement test system and a test method. The test system comprises a gas storage tank, a water storage tank, a test container, a sump and a weighing system used for measuring the weight of water entering the sump. The test container is communicated with a branch pipe used for mounting a tested valve. A valve opening height detector is arranged on the tested valve. The gas outlet of the gas storage tank is communicated with the water storage tank. The water outlet of the water storage tank is communicated with the test container. The water outlet of the tested valve is connected with the sump. Gas in the gas storage tank enters the water storage tank to continuously feed water in the water storage tank into the test container until water is discharged through the water outlet of the tested valve. According to the invention, for the micro-open-type safety valve, incompressible water is used as a test medium to ensure that only water flow through the tested valve; and the displacement of the tested valve can be accurately measured.

Description

technical field

[0001] The invention belongs to the technical field of safety valve testing, and in particular relates to a displacement testing system and a testing method of a micro-opening type safety valve. Background technique

[0002] The safety valve is a valve that opens and closes automatically by the force of the medium, and is usually used as the final protection device for pressure-bearing equipment. The opening performance and discharge performance of the safety valve are the main factors that must be considered when selecting a safety valve. At this stage, the performance of the safety valve is mainly obtained through the test of the test device. A scientific and reasonable design of the test device is the premise of accurately testing the performance of the safety valve. There is no accurate measurement technology for the discharge performance of the micro-opening safety valve in the prior art. Contents of the invention

[0003] In order to solve the above ...
